Sorry, it is not clear what you are trying to do. There are a few clear mistakes in your rule: 1. You can't use the $totV variable inside the accumulate, since $totV is the "result" of the accumulate. 2. You can't use variables bound inside accumulate outside of it, since accumulate is a scope delimiter ($ciNo, $ciLineNo). 3. If you want to sum values, use sum() function, but if you want to count occurrences, use the count() function. 4. This expression is wrong: "$totV > 1". You must either compare something to a field or use an "eval()" (inlined or not) to evaluate arbitrary expressions. 5. I think it is simply a typo, but since the DRL is case sensitive, the java class Number must be written with capital N. Maybe if you can explain with more common terms what rule you are trying to write, we can help more... the best I could imagine is: rule "00910 Pass XV sets" when $status : ValidationPassFailStatus() exists ValidationControl(validationNo == 910) CiLines( $ciNo : $ciNo, $ciLineNo : $ciLineNo, spiSecondary == "X" ) Number( intValue > 1 ) from accumulate( $c : CiLines( ciNo == $ciNo, ciLineNo == $ciLineNo, spiSecondary == "V" ), count( $c ) ) then $status.pass(910); end Hope it helps.
